ABSTRACT:
A variable rotary cutter assembly for transverse cutting of web material as it passes between rotating anvil and knife cylinders includes one or more cutter assemblies selectively positionable on the periphery of the knife cylinder. Various embodiments of the cutter assembly include a pair of pivotally connected block members adapted for releasable mounting on the knife cylinder and carrying an elongated knife blade which is biased outwardly by spring means about a pivot axis parallel to and spaced from the knife blade. The spring means enable a precise predetermined cutting pressure per unit length of the knife blade to be established against the anvil cylinder while enabling self-adjusting movement of the knife blade to accommodate substantial variance in anvil and knife cylinder spacing and knife blade wear. The cutter assemblies may be mounted to effect single or double transverse web cuts, and stripper means are provided to remove trim strips cut from the web by pairs of knife blades.
